TALKING MACHINE.

'Application led May 6, 1925, Serial No. 28,444, and'in Great BritainMay 14,1924.

This invention relates to improvements in talking machines and inparticular to improved means of mounting a large diaphragm, adapted toplay without a soun-d The object of the invention is to enable thediaphragm to be so mounted that it is easily handled for changing thereproducing needle and for inserting the needle in the sound line.

According ,to the invention a talking machine is provided in which adiaphragm of the type referred to above has the stylus holder mountedlat ornearto its edge, said diaphragm being' mounted to rock about a.point substantially diametrically opposite the stylus holder so thatthe stylus can move both transversely across the'record and vertically.

The diaphragm may be mounted tolie in any convenient plane duringplaying; for example it ma \lie in a plane inclined to that of therecordfor turntable.

In constructions of talking machine embodying' this invention it may befound advantageous to mount the diaphragm in such a' manner that it can'be moved, when notl in use, into a position substantially parallel withthe record, so that the cabinet of the machine shall not require to beof unusual depth between the lid and the motor board.

The invention is illustrated by way of eX- ample in the accompanyingdrawings in which Fig. 1 is a side elevational view of a machine withthe parts in the playing position. 85 Fig. 2 is a similar View to Fig. 1but with the parts in the non-playing position.

. Fig. 3 is a rear elevational view ona larger scale showing thediaphragm carrying means.

Referring to the drawings, 1 is the dia- 4 phragm carried within a stiffholding rim 2,

said 'diaphragm and rim lying .during playing,'as will be seen from Fig.l, in a plane in- I clined to thatof the turntable 8. VThe stylus holder4 is mounted on the front or lower end of the diaphragm holding rim 2and is maintained in position by bolts or the like passed through therim 2, and a member 5 eX- tending from the centre of the spider v6 and osecured to said stylus hol-der 4 by screws 7 or other suitable means.Upon the rear arms 8 of the spider is mounted, by means of bolts or thelike, a flat plate 9 and to this plate is needle across the recordduring playing.rr

The pillar `17 is rigidly mounted upon a plate 18 adapted to rock abouta horizontal aXls determined by bearings formed by screws 19 andlock-nuts 20 carried in lugs 21 upstanding from a plate 22 screwed tothe motor board 23,-which engage in recesses formed in the sides of theplate 18. ALugs 24 are provided on the plate 18 to arrest the rotationof the latter in one direction (clockwise in Figs. 1 and 2) byengagement with the plate 22. Movement in the opposite direction islimited by the engagement of the end face 25of the plate 18 with anadjustable stop screw 26 projecting upwardly from the base plate 22. Astrong leaf spring 31 is provided on the base plate 22 which serves tomaintain the plate 18 and the parts which are carried thereby, in eitherof the two alternative po-` sitions; i.-e. in the playing position shownin Fig. 1 by upward pressure against the under surface of the plate 18and in the non-playing position shown in Fig. 2 by upward pressureagainst the forward end 25 of plate 18. The front end ofthe lug 24 onthe same side as screw '26 is cut awayas shown at 27 so that it shallnot foul said screw 26 during movement. 28 is a collar, adjustablelongitudinally of the rod 16 and carrying a spring 29 which engages withan extension 30 of plate 9 bolted to spider arms 8 to take a portion ofthe weight which would otherwise rest, through the stylus, upon therecord.

The weight with which the stylus restsupon the record can be v aried atwill by moving the collar 28 up or Idown the rod 16.

During playing, up and down movement of the diaphragm, necessitated, forexample, by a turntable or record -not rotating in al true horizontalplane, takes place about the horizontal axis determined by bearingscrews 13 and rod 15, while the movement of the stylus across the recordis permitted byrod' 16 rotating about the vertical pillar 17.

, When it is desired to move the diaphragm from the position of playingas shownl in Fig.l 1, the diaphragm is pulled vto the left and the rod16, pillar 17, and plate 22 are 4moved about the horizontal axis, formedby pins 19, against the pressure of spring 31, untilthe position shownin Fig. 2 is reached; This arrangement obviously requires much lessdepth between thefturntable and the top of the lid of themachine whenclosed than would be the case if the diaphragm remained in the raisedplaying position.

I claim: v

1. In a talking machine of the large diaphragmtype wherein a recordturntable is mounted above a motor board, a supporting spider for thediaphragm, a stylus carried by the spider-'and operatively connected tothe diaphragm, and means coacting with said stylus to support saiddiaphragm Jfor playing in a plane inclined with respect to said. I

turntable, said means including a member pivoted to tlievmotor board atone side of said turntable, and means, permitting movement of thediaphragm in vertical and horizontal planes, -mounted on said member andsecured to said spider at a point substantially diametrically oppositesaid stylus.

2. In a talking machine of the large diaphragm type wherein a recordturntable-ius mounted above a motor board, a supporting spider for thediaphragm, a stylus carried by the spider and operatively .connected tothe diaphragm, and means coacting with s aid stylus to support saiddiaphragm for playing in a plane inclined with respect tosaid-turntable, said means including a member pivoted to the motor boardat one side of the turn?l in an inclined playing position relative to.

the turntable, said means including telescoping members, and meanspivotally connecting one of said members'to the motor board to permitmovement of the diaphragm to nonplaying position substantially parallelto the turntable. f

4. A talking machine of the large diaphragm type wherein a turntable isrotatably mounted above a motor board, a stylusl vmounted adjacent theedge of the diaphragm and operatively connected to the latter, meanscoacting with thestylus to support said diaphragm for playing in a planeinclined with p respect to said turntable and said means including anormally stationary pillar'secured to the motor board at one side of theturn- 5. In a talking machine of the large diaphragm type wherein arecord turntable is mounted above a motor board, a mounting for thediaphragm comprising a plate secured to the motor'board atone side ofthe turntable, a pillar pivotally secured to said plate and adapted tobe moved to a position substantially parallel with the motor board,means yiedingly maintaining said 'pillar in an upright position, a rodpivotally mounted on said pillar, means operatively connecting saiddiaphragm and rod, and yielding means carried by the rod. adapted toengage said lastnamed means when the diaphragm occupiesl a playingposition.

6. In a talking machine of the large diaphragm type -wherein a recordturntable* is mounted above a motor board, a mounting for said diaphragmcomprising a plate 'secured to the motor board at one side of theturntable, a pillar pivotally secured to said plate, means foryieldingly maintaining said pillar in'a substantially vertical position0r 4in a position substantially parallel with the motor board and meansmounted on the pillar and secured to the diaphragm for permittingmovement of the diaphragm in vertical and horizontal planes. Y

7. A mounting for a talking machine diaphragm comprising a diaphragmspider, a

pivotally mounted supporting pillar, means connecting said spider andpillar permitting movement of the diaphragm in vertical and horizontalplanes, and a yielding element adjustably secured to said last namedmeans and normally having engagement with said spider, said yieldingelement being adapted to support said lastnamed means when the diaphragmis moved to non-playing position.

' 8. In a talking machine of tlie large diaphragm type wherein aturntable is rotatably mounted above a motor board, a normally uprightpillar pivotally secured to the motor board at one side'of theturntable, means including a spider 'for pivotally securing fthediaphragm to said pillar and adjustable means including a resilientmember supported by the pillar and having abutting engagement with thespider when the diaphragm is in playing position, said resilient meansbeing adapted to engage sald motor board to yieldingly support saidpillar when the diaphragm is moved to a position substantially parallelwith the motor board. 5
